My boss just purchased me a 2015 PM 1500 / 136 length / high top / eco diesel. After a 3 month search we found one just outside of Tulsa, OK. Its like brand new with 3800 miles on it. Well...until I put 1600 miles on it in 3 days. I'm looking to do a partition. Its so loud and on blue tooth it sounds like I'm yelling from the back of the van. Some partitions look to be right against the seats. Any suggestions?
